UNITED STATES PATENT OFFICE.

SMOKE AND CINDER CONDUCTOR.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed November 24, 1905. Serial No. 288.901.

To all whom, it may concern.-

Be it known that I, HENRY LEON LARI- SEY, a citizen of the UnitedStates, and a resident of Charleston, in the county of Charleston andState of South Carolina, have invented a new and Improved Smoke andCinder Conductor, of which the following is a full, clear, and exactdescription.

The invention relates to railroad trains, and its object is to provide anew and improved smoke and cinder conductor, arranged to conduct thesmoke and cinders from the smoke box of the locomotive back over thelocomotive tender and cars of the train, to increase the draft andprevent back draft in the fire box when the doors thereof are opened, toinsure a free exhaust and thus relieve the locomotive engine of backpressure.

The invention consists of novel features andv parts and combinations ofthe same which will be more fully described hereinafter and then pointedout in the claims.=

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a longitudinal sectional elevation of a locomotive providedwith the improvement; Fig. 2 is an enlarged transverse section of thesame, on the line 22 of Fig. 1; and Fig. 3 is a plan view of the valve.

In the drawing A is a locomotive and B the smoke and cinder conductorhaving its forward end secured to the smoke box A of the locomotive.This conductor extends rearwardly over the locomotive and is held in asupport E projecting from the locomotive. It is to be understood thatthe conductor is to extend to the rear of a train so that the smoke andcinders passing into the conductor leave the same at the rear of thetrain, thus preventing them from entering the cars.

In order to prevent back draft in the locomotive, the followingarrangement is made: The entrance end of the conductor B is adapted tobe closed by a valve F fitted to slide longitudinally on suitableguideways A arranged within the smoke box A, as plainly shown in Figs. 4and 5. The valve F is connected, at its under side, with a rod Gextending rearwardly through one of the smoke flues A of the locomotiveboiler, the rear end of the rod G extending in the fire box A andconnecting with a lever H pivotally connected with a lever I connectedby a link J with the firing door K, so that when the latter is opened,then a sliding motion is given to the valve F by the connection abovedescribed, so that the valve F is moved from its normally open positioninto a closed position, to disconnect the'conductor B from the smoke boxA of the locomotive. When the firing door K is closed, a return slidingmovement is given to the valve F to move the same into an open positionto connect the smoke box A with the conductor B for the escape of thesmoke and cinders, as previously explained.

In order to provide a free exhaust of the locomotive engine in either ofthe two positions of the valve F, the latter is provided with openings Fand F of which the large opening F is usually in register with theadapted to register with the exhaust nozzle at the time the door K isopened, to allow at all times a free escape of the exhaust steam intothe conductor B, no matter whether the valve F is open or closed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A smoke and cinder conductor for railroad trains,comprising a conducting tube leading from the smoke box of thelocomotive, and a valve controlling the admission of the smoke andcinders to the said tube and connected with the firing door of thelocomotive furnace, to close the valve on opening the firing door.

road trains, comprising a conducting tube leading from the smoke box ofthe locomotive, and a valve controlling the admission of the smoke andcinders to the said tube and connected with the firing door of thelocomotive furnace, to close the valve on opening the firing door, thesaid valve having openings adapted to register with the exhaust nozzlefor the passage of the exhaust steam.

3. A smoke and cinder conductor for railroad trains, comprising aconducting tube leading from the smoke box of the locomotive, a valvecontrolling the admission of the smoke and cinders to the said tube, anda rod and lever mechanism connecting the said valve with the firing doorof the locomotive furnace.

4.. A smoke and cinder conductor for railsmoke stack and the smallopening F is 2. A smoke and cinder conductor for railroad trains,comprising a conducting tube leading from the smoke box of thelocomoti've, a valve controlling the admission of the smoke and cindersto the said tube, and a rod and lever mechanism connecting the saidvalve With the firing door of the locomotive furnace, the said rodextending from the smoke box through one of the smoke tubes of theboiler into the fire box thereof.

5. In a smoke and cinder conductor for railroad trains, the combinationWith a locomotive, of a conducting tube leading from the smoke box ofthe locomotive, a valve Within the smoke box for closing the end of theconducting tube opening into the smoke-box, and a lever mechanism foroperating the valve from the firing door of the locomotive. 6. In asmoke and cinder conductor for railroad trains, the combination With alocomotive, of a conducting tube leading from the smoke-box of thelocomotive and extending rearwardly, a valve mounted to slide Within thesmoke-box below the end of the conducting tube opening into thesmoke-box, a rod secured to the valve and extending rear- Wardly throughone of the smoke lines of the locomotive boiler, a pivoted lever towhich the rod is pivoted, a second pivotedlever pivoted to the firstnamed lever, and a link connecting said second lever with the firingdoor of the locomotive.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
